IMPROVEMENT IN FODDER-CUTTERS.

Specification forming part of Letters Patent No. 202,553, dated April16, 1878 application filed February 2, 1878.

To all whom it may concern:

Be it known that I, GEORGE KNOTH, of Breslau, in the county of Suffolkand State of New York, have invented a new and useful Improvement inFodder-Gutters, which improvement is fully set forth in the followingspecification, reference being had to the accompanying drawing, in whichFigure 1 represents a front view of a machine embracing my invention.Fig. 2 is a vertical section thereof in the line w :12, Fig. 1. Fig. 3is a front view of one of the oblique knives. Fig. 4 is a side view ofone of the circular knives.

Similar letters indicate corresponding parts.

My invention relates especially to that class of machines used forcutting corn-stalks and similar substances; and it consists in a seriesof circular knives, which are secured on a suitable shaft and providedwith recesses in their peripheries, in combination with oblique knives,which are inserted in said recesses and fastened at their opposite ends,so that an effective union between the knives is obtained. and one whichpermits of detaching any of the knives with facility, while, by thecombined action of the circular and oblique knives,

corn-stalks or similar substances can be out both lengthwise andcrosswise in one operation.

In the drawing, the letter A .designates the circular knives, and B arethe oblique knives, of my cutter. O is a shaft, on which the circularknives are secured, and a are recesses formed in the latter for thereception of the longitudinal knives. I secure the circular knives A onthe shaft 0 by means of a featherkey, as shown in Fig. 2, and to permitof giving a revolving motion to said shaft, I provide the same with acrank, D. The oblique knives B and the recesses a have a tapering form,so that when these knives are inserted in the recesses they are heldagainst a radial movement. For the purpose of holding the shaft, F,which, in the example shown, is

geared with the knife-shaft (J by means of cog-wheels G H. The shafts Oand F have their bearings in a frame, I, forming part of a trough, J, inwhich the substances to be out are placed, and which serves to conductthem between the roller E and the knives.

When a revolving motion is imparted to the knife-shaft O, andcorn-stalks or other substances are fed between the knives and theroller E, the stalks are cut by the circular knives A into lengths equalto the distances between the circular knives, While at the same time thestalks are split lengthwise by the oblique knives.

By uniting the circular knives A and the oblique knives B in the mannerstated, I am enabled to detach any of the knives for the purpose ofsubstituting anew one, or for any other purpose, and also to put themtogether with extreme facility.

What I claim as new, and desire to secure by Letters Patent, is-- Thecombination, in a fodder-cutter, of a series of circular knives securedto a suitable shaft, and having recesses in their peripheries, withoblique knives, which are inserted in said recesses and fastened attheir opposite ends, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 26th day of January, 1878.
